Great but I am not sure why I was placed in zone 4 for boarding despite being an Infinity Member??? Can you explain online. Thanks

basic and only minimum of service, they offer nothing special

The staff was marvelous. The entertainment options were terrible, old or 2nd rate movies. I was unable to entertain myself for 18 hours-it made it seem even longer. Note: I thought about upgrading but your information about what was included was unclear. Are the seats bigger? Are there current moves? What kind of food do you get? Would the upgrade compare to Delta? Just saying the upgrade is better didn’t convince me and I regret not flying Delta.

Good experience but could be better for people with injuries and needing extra assistance

The employees were professional and efficient. I consider myself a traveler but have trouble with the international fare served on airplanes. I admit Americans buy their food in the supermarket and we typically don’t eat the ligaments and cartilage. I know that is whiny but as I age, I dislike it more. At least things weren’t covered in cheese. The desserts are terrible! My neighbor didn’t eat her bread so I asked if I could have it. First time for everything but had been traveling a total of 27 hours and was hungry.

Plane is new and I was upgraded to first class so all was great.

The flight from Taipei to LAX was the first time we encountered rudeness from the crew. From the gate agents to the in flight crew. We had received such wonderful service going to Bali and on our Bali to Taipei flight that it shocked us when the gate agent was rude and then the rudeness continued on the flight to LAX.

Overall great experience. All four members of my family were seated together without paying extra to reserve seats. Everything was on time. Food was great and healthy. Media entertainment was good. Rock music could be added as a listening choice. No issue with baggages. Flight attendants were friendly and helpful. I would recommend EVA to friends and family.

I was expecting that movie selection and food would have been better. Everything else was great.

Flight was smooth no complaint. Except maybe better food choice for the long flight…

Seat width can be a bit wider. not nice that they charge extra for the window seats. online check in can be greatly improved. in other words, their online interface is bad.

I was very happy with my flight on ANA. The crew were excellent and very helpful throughout the flight. The food was also very good. The seats were comfortable and had excellent legroom. The headphone jack position was annoying, but that is a minor nitpick. The movie selection in the IFE was good, but the TV selection was lacking. Adding English subtitles to the Japanese movies and videos would have been very useful.

Seats had more space than expected. No recline, that is good.

Everything was excellent except for the hot cabin during the two trips. Why would you keep the cabins cool hot?

Loved that leg room was great for economy, and food was definitely better than other American airlines, great selection of movies. My mom is happy.

Just okay. Staff is accomodating especially at the check in counter and gate. Boarding was just fine. Leg room was cramped at economy. No entertainment, wifi is so-so. Cola in can given by cup, but rest of can was not given. At least give the whole can.

What I noticed is that when customers or passengers are asleep, they are no longer given food.

Flight were late each leg of the trip, seats were narrow and uncomfortable. Food was delayed and poor quality. Overall a bad e perience. I complained and was offered no offset or compensation.

Flights were late on every leg of the trip. Seating was narrow and uncomfortable, and food was below average. I complained directly to the crew, and ANA, and was offered no offset or compensation.

I ask the crew to help me get my bag because I can't reached it she ignore me

Website from the 1990s, super frustrating customer support, inflight experience merely OK - more like United than e.g. Emirates

The seats are significantly more comfortable than US airlines and the staff are much friendlier. The food is also much better, as they are particularly accommodating to any dietary restrictions.

Could had been better if they include in their menu some western food.

They 7 seats in one row for Business class while most business class for other airlines are 4 seats in one row. the seat was narrow. the Toilet was so smell, dimming light, no water out of faucet. Terrible.

Difficult to access advanced check-in online. No way to understand why it wouldn’t work. Call center not answering. Email for answers took days to respond, Kind service at the airport and on the flight made up for disappointing service before flight.

Attentiveness by crew was very good. The seats were uncomfortable seemingly too hard with inefficient cushioning. This was verified with my traveling companions. Also the incline button was inoperable.

Courteous and helpful employees. Comfortable seats and temperature of aircraft . Did not need squid in my salad but glad to have the menu information advising me of what it was

Everything was great, except the Wifi, but that's understandable.

The plane was dirty, there was trash in the seat pocket in front of me.

Food was excellent, the crew was exceptionally friendly, and the seats were comfortable. Bathroom were also kept very clean and odor free.

It was very good experience on board to Sydney with SQ.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

Flight was delayed by baggage loading onto the plane. This was attributed to "inclement weather" (some moderate rain) which could be said to be beyond the airline's control, but the problematic part was that the plane was boarded and doors shut so that passengers sat in a cramped plane with rising temperature (full flight) for an hour. The airline was aware of the status of baggage loading, they could have deferred boarding to keep passengers comfortable.

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

Service excellent would chose Singapore airlines as my first choice

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

I liked all the informational texts. I always knew where to go and when .

I feel bad, but Swiss airlines is not an airlines I will ever fly again. Their cabins are basic, seats are extremely uncomfortable, crew is a hit or a miss with service. What's worse is how they make you feel they are there to make money and not make your travel needs be met or make your travel a pleasure. They charge for 2nd bags, seat selection and felt like a budget arinines frontier/spirit airline attitude and approach. Their business class is from the early 2000s, basic. Additionally, planes going to India, are old, falling apart and not maintained. Even the crew mentioned this is typical of the airline having older planes going to India. Panels detached and loose or stuck with duct tape, seats scruffed up and dirty, seatbelts roughed up. The scariest thing was when I saw a window panel next to where I was sitting loose and dangling. The crew mentioned it's only cosmetic and assured the integrity of the plane was inspected by the maintenance crew. This is where they confessed about planes going to India being old. I UNFORTUNATELY would NOT recommend Swiss airlines to anyone and will NEVER fly with them again!

Very punctual. Comfortable plane and great entertainment options. The staff was very nice.

Liked the hospitality . The ight took us 6 hrs to get from fort myers to ewr.

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

Change cabin crew assisting business class. Not taking care, ignoring requests and calls. Never had such an experience in business class.

The ANA crew and their members were all extremely nice and caring. Shout out to the crews for working on Christmas and New Years. Y'all the real MVP

Not as good as expected Air Can needs to improve totally rated on internet as worst

The flight attendants in First Class were mediocre at best. They did not take our tray away until we were about to land and only did so when I press the call button. The United person at the United Club was asked to get us our boarding pass since we missed the flight due in Chicago. She argued that we did not have seats on the flight given to us in Moline. Furthermore, she was adamant that we did not have a First Class ticket. After I spent much time with her trying to show we were correct, she reluctantly agreed. She was probably the most incompetent ticketing person I have ever met and I have traveled 3 million miles on United plus many additional miles with other carriers. United has definitely deteriorated in more than on way.
